Step-by-step explanation:
Assume year 2000 as t, that is t =0.
Formula:

Where,

for doubling time,


Given value:



when year is 2000, t=0 so, year is 2100 year as t = 100.

Answer:
V = x(19-2x)(4-2x)
Step-by-step explanation:
We are given;
Length of flat piece of material =19 inches
Width of flat piece = 4 inches
We are told that the open box is to be made from a flat piece by cutting equal squares of length x from the corners and folding up the sides
Thus, we will now have;
length of open box = (19-2x) inches
Width of open box = (4-2x) inches
Height of box = x inches
We know that: Volume of box = length × width × height
So, plugging in the relevant values, we have;
Volume of box(V) = x(19-2x)(4-2x)
The second choice becouse of the total being changed
